Hi all,
Is there any way to determine which functions are available on which
platforms? For example, winProgr essBar (and related functions) are
only available on Windows, but what about tkProgressBar and
txtProgressBar? Is there any way to figure out which functions are
only available on certain platforms, without installing R on that
platform and checking?
Generally I think the only reliable way is to look at the source. Things in
"windows" subdirs, or marked off with "#ifdef windows" (in Rd) or "#ifdef
Win32" (in C) are for windows only. Probably our documentation should point
out when something is platform-specific, and frequently it does, but I don't
think it is completely consistent in this.
To me it seems like it would be easier to include the all functions
all on platforms, and then return an error on platforms where they
aren't supported. The problem I'm now having is that I'm now getting
an warning when building my package because it can't link to the
documentation for winProgressBar. Should I just ignore that warning?
<bromide> It's better not to ignore warnings. </bromide>
I'd suggest wrapping the link in "#ifdef windows" (assuming it's in an
Rd file).
